Do Ants Dig Better In Light Or Dark Science Fair Project

Ants are a great insect to use as a test subject in a biology science fair project. They are easy to find and they are easy to handle. In this sample project students will be manipulating the amount of light that ants are exposed to in order to see if light impacts how fast ants dig.

Hypothesis

In this science fair project the hypothesis is that ants dig faster when they are in the dark. The dependent variable in this hypothesis is the rate at which ants dig and the independent variable is the amount of light that the ant is exposed to during their digging session. It is important to note that a non-venomous ant species be used, such as a sugar ant.

Supplies

This science fair project will need an ant-farm set-up. Students can purchase an ant farm or they can develop their own using a glass container filled 75 percent of the way with native soil. Students will also need a test population of ants. Ants can be purchased from a science store or collected out on the schools playground. You can set traps for ants using cut apples. Just set the apple on the ground and wait until ants cover it. Then pick up the apple pieces, with the ants and place them in your container.

Experiment

The control experiment will provide the ants with a natural light source. Students may want to use a video camera with a digital timer display to monitor the ants digging progress.

The test experiment will involve several test groups. The first test group will be exposed to no light at all, an infrared camera will be used to monitor their digging progress. The second test group will be exposed to dim light. The final test group will be exposed to bright artificial light.

Data Collection and Analysis

The data that will be collected will be measurements of digging per time period. The students will want to determine how long of a tunnel is dug in a minute, in an hour or in a day for each lighting situation. To determine the rate of digging the student will create a ratio of millimeters dug per minute.

The analysis of this data will be fairly easy to complete. The students will just need to determine which lighting set-up produced the fastest rate of digging, or the highest number of millimeters per second (on average). To prove the hypothesis could be true students will need to find a trend where ants dig faster in darker conditions then they do in lighter conditions. If this is not observed then the hypothesis will be proven to be false.

New Technology Could Increase Fertility Treatment Success Rates

The fertility treatment industry and the medical field in general are no strangers to new technology making its way into the field. Innovative procedures and treatments are introduced consistently in the medical industry, with research being conducted every day to help improve the lives of people and, in the fertility field, to help couples conceive.

In vitro fertilization may be a staple among assisted reproductive technologies, as many people have become familiar with the procedure that combines an egg and sperm in a dish in a laboratory so that an embryo may form and be placed in the woman’s uterus where she is expected to carry it to term. With innovations in the field, the success rate of IVF has increased consistently through the years.

Preimplantation genetic diagnosis allows doctors to determine if any genetic defects exist in embryos used in the in vitro fertilization process. By diagnosing genetic disorders in embryos before they are used in an IVF procedure, many scientists and doctors believe that this has helped to cut down on genetic defects at birth and has improved the success rate of IVF.

Still, there are those looking for other ways to increase the in vitro fertilization success rate. Using a procedure called Array Comparative Genomic Hybridization (Array CGH), scientists believe that the new technology will increase the success of fertility treatment.

In this procedure, about 8 to 10 cells are removed from a blastocyst embryo on the fifth day following retrieval. The cells are then tested, which many believe has led to an increase in the IVF success rate. The procedure may require a couple of weeks before results may be obtained, which requires that the embryos are cryo-pressed and transferred in another treatment cycle. Research is still being done regarding this new technology in fertility treatment, including whether there are any adverse effects on the embryo throughout this process.

Couples and patients who are interested in this new technology and other fertility treatments should speak to a medical professional at a fertility clinic in their area for more information. In cases where couples have gone through several treatments with no success, exploring other options may be helpful. For couples and patients new to treatment, utilizing a proven treatment may be the best option. Of course, this is a decision that couples must make amongst themselves and with the guidance of a medical professional in the fertility services field.
